Rap duo Macklemore & Ryan Lewis have scored a fourth week at the top of the U.S. pop charts with a rare five-week run of 300,000-plus digital sales.

Only four songs have been able to match that feat, and they include 2013 Grammy Award winners fun. (We Are Young) and Gotye (Somebody That I Used to Know).

Since its release last month, MACklemore & Lewis' Thrift Shop has sold three million copies.

The duo keeps Bruno Mars' former number one Locked Out of Heaven stuck at two, while will.i.am and Britney Spears' Scream & Shout remain at three.
